FIELD: test and measurement equipment.
SUBSTANCE: invention is intended for use in devices for measuring flow rate of hot water. Hot water counter impeller comprises drive magnetic coupling, which is placed in sealed container made of nonmagnetic material, filled with magnetic fluid.
EFFECT: technical result is directly proportional dependence of rotation speed of driven half-coupling from temperature of water passing through counter.
